Train of thought of a tired mind

Train of thought of a tired mind, right after putting M to sleep, while emptying the dishwasher: "It's really great that we have so many plastic dishes so the noise doesn't wake M up... It's weird that they thought about not waking babies up when making plastic dishes... Oh, they didn't... They're actually plastic so they wouldn't break... Why would they break though? Why aren't all dishes plastic then?" I should stop talking to myself.
